To all whom it may concern:

Be it known that I, RALPH G. TAYLOR, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a full, clear, and exact description.

My invention relates to dumping cars and particularly to the means for holding the drop-doors thereof closed.

Heretofore cars of this type have been so constructed that the doors were hinged directly or indirectly to the flooror parts of the floor construction, and this caused the load to hear more heavily on the parts to which said doors were hinged, and thus wore out the car much sooner than would otherwise have resulted. The construction of the underframe of many dump-cars has generally been such that the doors were ver narrow and quite a platform extending t e entire length of the car was left between the doors on each side of the centersills that had to be shoveled off by hand after the doors had been dropped. In addition to this, the shaft on which the chain that retained the doors in their closed position, was wound, was held in the desired osition by a ratchet and pawl that were liablb to become accidentally disengaged by the jar and shaking of the car while in motion and let the doors drop and discharge the load carried thereby, oftentimes causing not only loss of the freight, but the derailment of the car as well.

The objects of in invention are to relieve the floor of the car rom an unequal distribution of weight, and to increase the superficial area of that portion of the floor composed of said drop-doors, and reduce the area of that portion of the floor requiring to be shoveled off after the doors have been dropped and thereby enable the car to be unloaded quicker.

A further object of my invention is to provide means for retaining the doors closed that will not shake or jar loose and permit the accidental dropping of said doors.

These objects I accomplish by the means hereinafter fully described, and as more particularly pointed out in the claims.

In the drawings:Figure 1 is a side elevation of one end of the body of a gondola car embodying my invention. Fig. 2 is an end elevation thereof. Fig. 3 is a transverse section of said car taken on dotted line 33, Fig. 1, drawn to a larger scale, and showing the drop-doors in their closed position. Fig. 4 is a similar view showing the dro )-doors open. Fig. 5 is a detail view on a sti larger scale showing a transverse section of the lower portion of one side of the car-body with t e drop-door locking mechanism in side elevation. Fig. 6 is a. longitudinal section of the same part of the car looking at the outer end elevation of said locking mechanism. Fig. 7 is a detail view showing an outer edge elevation of a modified form of the hooks of said door-locking mechanism. Fig. 8 is a side elevation thereof, Fig. 9 is a plan view of the same.

The drawings illustrate the body of a gondola car to which my improvements are applied, and which consists of sheet metal sides a, riveted or otherwise secured to rolled metal posts I), 1), whose lower ends extend below the plane of the floor of the car, and are secured to the ends of the transverse needlebars and bolsters A, by means of metal angle-plates 0. These angle-plates are, preferabl made of cast metal, and are provided wit 1 joumal-boxes d, d, for a longitudinally disposed shaft C, and may be either riveted thereto, as shown, or cast in one piece therewith (not shown).

The needle-bars extend, as shown from side to side of the car, and pass through suitable 0 enings in the single center-sill D, which fatter consists preferably of a single I beam of such dimensions that the said needle bars can pass through 0 enings in its web, and be secured thereto y cast metal brackets e, e, riveted to both bars A and sill D. Alongside of these brackets e hinge plates E are riveted or otherwise secured to the web of the center sill, and have arms f projecting out from their upper ends, that ave knuckles on their outer extremities to which the knuckles of the hinge-plates of the drop-doors F, F, are pivotally connected. A narrow strip of plate-metal g is, preferably, secured at its center of width to the top of the center-sill throughout the entire length of the car, and the doors F are of such width that when closed they form the floor of the car between the edges of the central floorplate g and the inwardly flanged lower longitudinal edges of the sheet metal sides of said car. These drop-doors are reinforced in any suitable manner and are provided with depending hangers G, the supportinglate of which is riveted or otherwise secure to the under side of the doors next the swinging edge of the same. Each supporting-plate is provided with a pair of these hangers adjacent to the side edges of the same, which curve towards the sides of the car and have a suitable ivotal bolt extended through open ings in -t eir lower ends on which the heel of a sickle-shaped hook H is pivoted. I prefer to make these hooks in pairs, so spaced apart by a pivotal boss that a hook will be next each hanger, and each air of said hooks are connected at about their centers of length b a cross-bar h, and at or adjacent to their extremities by a bar J.

When the doors are closed so that their swinging edges lap up against the inwardly flanged lower edge of the side of the car, the hooks H will extend over the shaft C and their under toothed edges engage the toothed wheels I. There are two of these wheels for each pair of hooks, and they are secured on shaft C in such position and so spaced apart by an integral drum K that t ey register with said hooks. The drum is rovided with spiral grooves in its circumerence, and at one end a chain is is suitably secured thereto that extends and is secured by suitable means to the cross-bar it.

By turning shaft C so as to unwind chain It, the hooks H will he moved back under the doors, and as the latter drop, will be held in such position by the pressure of said chain upon cross-bar J thereof; when the door is closed to such an extent that the pressure of said chain will not be against bar J, the hook will, as the chain continues to wind on drum K, engage and ride over toothed wheels I. When the doors are closed the shaft 0 will be locked, if the doors are located between the body-bolsters and ends of the car, by a ratchet and pawl mechanism m at the end of the car, as shown in Fig. 2 of the drawings, or by a pawl and ratchet mechanism n on the side of the car, as shown in Fig. 1. When the shaft C is thus locked the engagement of hooks H with the toothed wheel assists in sustaining the doors, and, should the chains break, will continue to hold thedoors closed, and if the pawl and ratchet mechanism becomes dise aged as well as the chains break said hooks ould continue to hold the doors closed.

In Fi 7, 8 and 9 I show a modified form of mec anism for keepin the dro -doors closed. In this modification I emp 0 but one hook O of about twice the width 0 hook H, and rovide it at about its center of length with a laterally projecting hi '0 to WhlGll one end of the chain is secured, and also provide it with a suitably curved arm Q near its extremity. The lug o is designed to take the lace of the cross-bar h, and the arm Q to ta e the lace of the c oss-bar J of the construction sliown in the rst six fi ures of the drawings. This modification 1s more compact, and dispenses with the necessity of two toothed wheels on the shaft C, and therefore economizes both space and material.
